[QUOTE="Lucky_P, post: 1001631, member: 12607"] Uterine prolapse - strictly a reproductive 'accident'; not a heritable or genetic defect, not due to any abnormality or inherent 'weakness' in any supporting structures. A cow or heifer that prolapses her uterus is no more likely to 'repeat the performance' than any other cow in the herd - or in the entire world, for that matter. I'd generally have no hesitation to keep a cow that had prolapsed her uterus. Now, with respect to glacierridge's prolapsed heifer whose dam prolapsed... there's likely no predisposition toward uterine prolapse outside of the possibility of an abnormally small or improperly-shaped pelvic canal - which probably IS heritable. Small/narrow pelvic canal --> hard/difficult delivery --> increased likelihood that the cow will 'feel the need' to keep pushing, because of bruising/swelling, etc., which can result in uterine prolapse. I manually prolapsed one one time, to suture a uterine laceration that had occurred while pulling a BIG calf (had a hard time getting it back in, 'cause of all the air that had rushed into the abdomen through the tear). With a wide-open cervix, it's not all that difficult to do - just reached in, got a good grip, and pulled that sucker right out. If the cow has had a difficult delivery and feels the need to continue 'pushing' due to bruising, etc. it doesn't take much to evert that uterus, and it's not because of structural unsoundness. Vaginal prolapse, now that's another story altogether. They tend to recur, and usually get progressively worse with subsequent pregnancies, and a heritable genetic predisposition has definitely been documented. Wouldn't keep one of those - or her daughters - and wouldn't use a son as a herdsire. [/QUOTE]
